> PMD create some default control rules with RSS action if it's not isolated
> mode.
> 
> However whether default control rules need to do RSS or not should be
> controlled by device configuration, the mq_mode of rxmode configuration in
> specific.
> 
> In another word, only when mq_mode is configured with
> ETH_MQ_RX_RSS_FLAG set, then RSS is needed for default rules.
